On February 12, 2024, Chugai, Genentech, and Hoffmann-La Roche filed a motion for voluntary dismissal of their appeals regarding the Patent Trial and Appeal Board’s (PTAB) decision in IPR2022-00578 and IPR2022-00579. The motion records that Celltrion (the petitioner) has not formally agreed to the dismissal and may file a response.
Previously, Celltrion filed inter partes review (IPR) petitions IPR2022-00578 against Chugai/Genentech/Roche’s MOT (RA) patent no. US8580264 (‘264), and IPR 2022-00579 against Chugai/Roche’s device patent no. US10874677 (‘677). The PTAB concluded that claims 1-12 of the ‘264 MOT patent and claims 1-8 of the ‘677 patent are invalid in view of the prior art. Chugai, Genentech, and Hoffmann-La Roche appealed PTAB’s decision and are now seeking to have that appeal dismissed.
